Product Description:
The MSK071D-0300-NN-M3-UG0-NNNN is an IndraDyn S synchronous servomotor produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. As a servomotor, it provides closed-loop torque and position control for automated axes in packaging machines, printing lines, and material-handling equipment. This type of motor is suited to applications that require repeatable motion, stable speed regulation, and accurate positioning during changing load conditions. When paired with a compatible drive controller, it can support coordinated start, stop, and positioning commands throughout automated machine cycles. A connector that rotates through 240° helps route the encoder cable in tight spaces without forcing sharp bends at the motor housing.
The motor uses frame size 071 with winding code 0300, a combination intended for medium-power applications that balance torque output with drive current demand. The enclosure carries an IP65 rating, which helps protect internal parts from dust and low-pressure water jets. Cooling is provided by natural convection, so the housing dissipates heat without a separate blower. Feedback is transmitted through the Hiperface interface, allowing position data and electronic motor information to pass between the multiturn encoder and the controller. The output shaft is plain and without a keyway, making it suitable for backlash-free clamp couplings. The motor is supplied with no holding brake, so a vertical axis must be supported by the drive or by external mechanics when power is removed.
The encoder provides 16 signal periods per mechanical revolution and also stores multi-turn position data, which reduces the need for a homing routine after power loss. Thermal endurance is rated to class 155, matching the insulation system used for the winding. Continuous operation is permitted at ambient temperatures from 0–40 °C, while higher temperatures require derating or additional cooling measures. The capacitive encoder sensing principle supports reliable signal quality in installations where vibration is present. That feedback arrangement helps the controller maintain rotor alignment during speed changes and short positioning moves.
